“Jeopardy!” host Alex Trebek, who took back the reigns of his show after a brief hiatus for brain surgery, proved Thursday that he was right back where he belonged by roasting the contestants participating on the night, on account of their lack of knowledge about the sport of football.

It is not uncommon to see “Jeopardy!” contestants fumble when it comes to answering sports-related questions. But on this particular night, it seemed like the game show contestants were absolutely clueless about the questions directed toward them from the category called, “Talkin' Football.”

The game show host was quick to catch on the contestants’ utter lack of knowledge about the topic when none of them even attempted to hazard a guess when it came time for them to reply. After observing similar grins on all of their faces, that made it quite apparent as to what they knew (or rather did not know) about the category, Trebek decided to have some fun and roast them on his show.

Here is a clip of the hilarious moments:

When no one buzzed after the second question, Trebek — pretty sure of how the rest of the segment would play out — sarcastically said: "Do you think we should take a commercial break?"

The contestants, knowing that it was a lost cause by then, and hoping that the rest of the category would just fly by, stood in their designated spots laughing and shaking their heads. The crowd, on the other hand, had a gala time cheering every time Trebek delivered a witty one-liner and taunting the contestant’s lack of football knowledge.

Updating his fans about his surgery in early January, Trebek said in a short videoposted on YouTube that it was caused by a subdural hematoma, or blood clots on the brain, as a result of a fall which occurred late last year. Following his announcement, the annual college championship on the show was pushed back to April.
